Quantum limits in optical communications
Seminar with Prof. Konrad Banaszek, University of Warsaw, Poland, expert on quantum physics and optical sciences.
The Gordon-Holevo capacity limit is reviewed as a unifying framework to identify attainable information rates in a variety of optical communications, ranging from conventional optically amplified fiber links to photon-starved scenarios in free space. Its role in the security analysis of continuous-variable quantum key distribution is also discussed.
Konrad Banaszek received the M.Sc. and Ph.D. degrees in physics from the University of Warsaw, Poland, respectively in 1997 and 2000. He held postdoctoral positions at the University of Rochester, NY and the University of Oxford, UK, eventually followed by a faculty appointment at the University of Warsaw, Poland. His field of research is quantum physics and optical sciences with a focus on novel approaches to communication, sensing, and imaging that enable operation beyond standard quantum limits. Currently he is the director of the Centre for Quantum Optical Technologies established in 2018 by the University of Warsaw in partnership with the University of Oxford under the International Research Agendas Programme operated by the Foundation for Polish Science.
